Abstract: In the present study, wave heights and dynamic pressures at the still-water level on half of a vertical cylinder surface are measured. Since the height is measured only between 0° and 180°, the symmetry of the distribution cannot be shown. However, Galvin and Hallermeier established in their study that symmetry existed in all cases tested. The purpose of this study is to show further that the height distribution follows crest distribution and dynamic pressure distribution which, in turn, suggests that even the pressure transducers around the structure may be used to establish direction of the wave.
